Deputy Justin Ferrari – of Florida's Volusia County Office – arrived on the scene after Victoria Rosado, 26, placed an emergency call on Sunday saying her ex-boyfriend was acting "crazy".

While on the line she hid from him in her bedroom as he continually attempted to break in.

After a three-minute call cops heard a scream and the line went dead.

On arrival Ferrari and his team of officers were swiftly shot at twice by the fuming ex.

In captivating footage Deputy Ferrari then moves quickly to rescue her three children – aged from 23 months to seven-years-old – picking one up and saying: "I've got you. I've got you."

The courageous cop then takes the kids to a secure building next door and breathes a huge sigh of relief at a job well done.

Viewers of the video were horrified and impressed in equal measure.

One LiveLeak user wrote: "The father should have left and shot himself and saved his children that trauma. Cop earned his day's pay good man."

And a third - in light of recent US police force criticism – added: "For those of you who bad mouth police or say disarm them watch this video and remember this could be your wife and kids. Remember that."

But this wasn't the first time the mum had suffered problems – just three days earlier police received a call about a verbal altercation.

Victoria is currently recovering from the assault and Emmanuel, 26, has been charged with three counts of attempted first-degree murder.
